I am testing my game in Steam and the achievement is granted, but I do not get any notification while playing.
I only found out when I returned to my steam library (where it also shows how many achievements you have obtained per game).
I tested in a resizable window, without the kiosk exported option.
C3 is used to build and export.
When testing in full screen, I do see the notification.
Does anyone have a suggestion on what I should do to make the achievement notification be visible while playing in a window?
Or does Steam perhaps not support notifications in a window?
